Old Beam Pump and Winding Engine, Glyn Pits is a post-medieval and modern colliery installation set upon the South Wales Upper Coal Measures Formation. The underlying geology—mudstone, siltstone, sandstone interspersed with coal seams, ironstone and ferricrete—dates to the Westphalian period and provided the mineral wealth that drove industrial activity in this landscape. The beam pump and winding engine represent the mechanical infrastructure essential to extracting coal and managing groundwater in deep workings.
The installation reflects the technological development of Welsh collieries during their period of maximum expansion and operation. Beam engines of this type were central to pit operations, powering both the winding of coal and miners to the surface, and the pumping of water from the mine workings. Such engines embodied the engineering advances that made deep coal extraction commercially viable across South Wales.
The monument is protected by Cadw under reference MM192. Its survival provides evidence of the industrial heritage and mining practices that shaped the economic and social character of Wales during the post-medieval and modern periods. The remains stand within a landscape fundamentally transformed by the extraction of the mineral resources that lay in the coal measures beneath.
